Filed: 1995-06-02
Abstract: PURPOSE: To provide the treatment with which organic waste water can be treated at a low cost without generating hydrogen sulfide and the maintenance of treating facilities can easily be performed by adding iron ions to the organic waste water in an amount expressed in terms of the number of moles equal to or more than that of sulfur compounds in the waste water and subjecting the waste water contg. iron ions to anaerobic treatment. CONSTITUTION: In this treatment, iron ions are added to organic waste water in an amount expressed in terms of the number of moles equal to or more than that of sulfur compounds in the waste water and the resulting organic waste water contg. iron ions is subjected to anaerobic treatment, wherein the anaerobic treatment is an operation for decomposing organic matter in organic waste water through acid formation reaction and methane formation reaction by utilizing the action of anaerobic microorganisms while maintaining the waste water contg. organic substances to be treated in an anaerobic state. Examples of waste water to which this anaerobic treatment can be applied are sewage, human waste, industrial waste water, etc., each of which contains a small amount of sulfur compounds such as sulfate and sulfite ions.  At the time of performing this anaerobic treatment, organic matter in waste water is decomposed through acid formation reaction and methane formation reaction effected by the action of anaerobic bacteria and on the other hand, sulfate ions, etc., are reduced to hydrogen sulfide by the action of sulfate reducing bacteria.

On the other hand, the temperature and humidity of the atmosphere are converted with an atmospheric temperature signal output section 2 and an atmospheric humidity signal output section 3 into signals, and is further inputted into input terminals 41 and 42 of an atmospheric dew point temperature computing unit 4 to be converted into atmospheric dew point temperature td. The signal tR and td thus converted are further inputted into input terminals 51 and 52 of an arithmetic unit 5 to be converted into a signal (tR-td). On the other hand, after the sunset as the road surface temperature falls, a signal is eminated from a sampling command section 11 to memorize 6 the measured values of the signal tR and tR-td at an interval of about 10min. A computing section 7 executes a regression calcula tion based on the memory data and a freezing decision section 8 forecasts the time at which the signal tr and the signal tR-td are both below zero. For example, a slippage caution alarm is outputted 30min before the forecast time, and a freeze warning 10min before.

Title: Collating method of handwritten input
Inventor: RICHIYAADO HARU
IPC: G06K9/62
Filed: 1995-06-27
Abstract: PURPOSE: To rapidly identify a handwriting by collating it with stored samples without converting it into a character code. CONSTITUTION: This method identifies a minimum speed point in scribble input locus like a pen input, etc. Next, the method collates an inputted handwriting by using three collating algorithms, i.e., syntactic, word, and elastic collatings. A syntactic collating module encodes a handwriting according to the shape of the handwriting in a minimum speed area. A word collating module encodes a handwriting according to the relative height against the baseline of a minimum speed point. An elastic collating module encodes a handwriting according to the sort of a minimum speed and an intermediate point. Finally, it decides an integrated collating result by executing a weighted mean of the results collated by those three modules.

Abstract: PURPOSE:To make constant a power amount applied to a heat element and eliminate unevenness in density irrespective of changes in applied voltage, by a method wherein a current loading time is controlled by comparing an integral value of the applied voltages with a reference value. CONSTITUTION:A current loading time to heat generating resistors R1-R1728 at a dot section is determined by an ON time of AND gates A1-A216 connected to bases of switching transistors Tr1-Tr216. That is, after a flip-flop FF is set, AND gates A1-A216 are turned ON, and a specific heat generating resistance part is energized with No.2 transistors TrG1-TrG8 ON. Simultaneously, a transistor FET becomes OFF, and an integral voltage is produced in a capacitor C1. When the integral voltage reduces gradually and comes down to below a reference voltage, then the flip-flop becomes OFF through the output of a comparator COM, and the capacitor C1 is cleared simultaneoulsy when the AND gates A1-A216 becomes OFF.
